To all whom it may concern:

Be it known that 1, Ivan D. 'lTr-ronnnnncn, a citizen of the United tltates, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful improvements in Apparatus for Assembling and Securing Ring-Liners to Can Ends, of which the following is a speci fication.

The hereinafter described. invention relates to means for positioning a gasket ring liner in axial alinement with a straight flanged unfinished can end, assembling the same relative to the flange of the said end and thereafter completing or finishing the can end so as to hold or retain the assembled liner relative to its flange.

In mechanism ordinarily employed for assembling gasket liners relative to the flange of a can end it is customary either to apply the ring liner to the edge of the can end and retain the same thereon by a curl being given to an upstanding circumferential flange or wall of the outstanding straight flange of the can end, or to assemble the ring liner relative to an uncurled outstanding flange of the can end having a circumferential groove formed in the outer surface of itsconnecting wall member by causing a distortion of the inner circumferential edge of the ring liner to permit of the same passing an overhang of the circumferential groove in the connecting wall member of the can end.

The object of the present invention is to dispense with the curl heretofore given to the upstanding circumferential wall of the flange of the can end and to dispense with grooving the connecting wall member of the flange prior to assembling or applying the gasket liner to the flange of the can end, and thus in the latter case, avoiding the necessity of distorting the inner circumferential edge of the ring liner as assembled relafive to the flange of the can end.

In the preferred embodiment of an apparatus for carrying out the hereinafter described invention, there isutilized means for feeding a straight flanged unfinished can end from a holder or magazine to a seat within a can end carrier, means for feeding a disk blank from a holder or magazine to within an aperture formed in a ring liner carrier turret, mechanism for cutting a ring liner from the positioned disk of gasket liner material combined with mechanism for actuating the turrets to position the cut ring liner in axial alinement with a positioned can end at an assembling station of the apparatus, and mechanism for assembling the liner relative to the flange of the positioned can end, and groove forming means for grooving the connecting wall of the can end after the gasket liner has been applied or assembled relative to the flange thereof, in order to secure or retain the gasket liner in fixed relation relative to the flange of said can end. While in the present case the apparatus is so constructed as to cut a gasket ring liner from a disk of liner material, it will be apparent that the ring liners may be fed to the rotating turret from a stack of previously cut ring liners, or that the same may be cut from a web of liner material, although, preference is given to the severing or cutting of the gasket liner from disks of liner material and transferring the cut ring liner to an assembling station and in axial alinement with a can end there positioned; the essence of the invention residing in the formation of a groove in the connecting wall member of the can end, for holding an assembled liner relative to the flange thereof after the said liner has been applied to said flange, and by so doing, preventing, obviating or overcoming the distortion of the circumferential edge of the ring liner as heretofore applied to a previously grooved can end provided with an outstanding flange, one form of such type of mechanism being fully set forth and described in my pending application entitled, Organized apparatus for grooving can ends and applying ring liners thereto, Serial Number 257,636, filed October 10, 1918.

In order to comprehend the invention as set forth in the preferred embodiment there of, reference should be had to the accompanying sheets of drawings, wherein,

In the drawings, the numeral 1 is used to designate any suitable form of a suitable frame capable of sustaining the working parts of the apparatus, and which, in the present case is formed with a top bed plate 2. Over the said bed plate 2 work two horizontally disposed movable turrets 3 and 4;, the former being provided with a series of spaced circumferentially disposed can end receiving apertures 5, and the latter with aseries of circumferentially disposed spaced liner receiving and sustaining apertures 6. The turrets 3 and a are mounted respectively on the upper ends of the vertical shafts 7 and 8, Figs. 1, 4 and 7 of the drawings. Can ends 9 to be grooved are maintained in stack formation within an open bottomed end holder or magazine 10 supported at one side of the machine by a bracket 11 projected from the frame of the machine, the stack of ends within the holder or magazine being upheld by the supporting blades 12, Figs. 1, 2, 5 and 6 of the drawings.

Above the bed plate 2 at a position substantially at right angles to the holder 10 is situated an open bottomed holder or magazine 14-, adapted in the present case to contain a stack of disk blanks 15 composed of suitable liner material from which the gasket lla ring liners 16 are cut, Fig. 10 of the drawings, said holder being supported by a bracket 17 projected from the frame of the apparatus and being provided with a projecting extension 18 adapted to partly overhang the turret 4, Figs. 1 and 4 of the drawings.

The shaft 7 carrying the can end apertured turret 3 is driven by means of a gear 19 secured to the lower end portion thereof, 12

Figs. 1, o and 7 of the drawings, meshing with a gear 20 secured to a lower vert cal shaft 21 within the frame of the machine, which said gear in turn meshes with a gear 22 fixed to the lower end of the shaft 8 for mittent movement is transmitted to the Geneva wheel 23 from the continuously driven vertical shaft 24 through'the' medium of the Geneva arm 25 securedto said shaft,

the followingroll26 carried at the outer-end thereof working in and out of the radial slots 27 formed'in said Geneva wheel. Motion is imparted to the shaft 24 from the horizontally disposed driven shaft'28 working within bearings 29 within the frame of the machine, bymeans of the bevel gears. 30 and 31, secured respectively to the shafts 28 and 24, Figs. Sand 4 of the drawings, and said shaft 28- is driven from the vertical shaft 32, mounted in bearings33 and 33 Figs. 2, 3and 4 of the drawings, by means of a bevel gear 34 secured to the lower'end thereof meshing with a similar gear 35 fixed to the outer end of the shaft28.

To the upper end of the vertical shaft 24 there is secured an under grooved cam 36, Figs. 3 and 4 of the drawings, with which coacts a following roller 36 carried'at'the inner enlarged end 37 of a reciprocating rod 37'. Said enlarged end 37 of the rod 37 is slotted to straddle the shaft 24, the outer end of the rod 37 being pivotally'connectedto the lower portion of a throw lever 38, pivoted at its lower end to a bracket 38' projected from the frame structure of the machine, Fig. 5 of the'drawings. The lever 38 at its upper end is connected by a link 39 to a horizontally reciprocating feed slide 39 Working within a guide-wayformedin'the upper surface of the supporting bracket 11 for the can end holden; As the slide is thrown inward the head thereof moves from between the rolls'12' o'f the-cut out blades 12 of the can end holder or magazine 10,.

' when the'tension of the spring 12 draws inwardly the outer ends of said out out blades, causesthe inner ends'to swing outwardly to release the stackof can ends withinthe holder. At apreviou's operation the lowermost can end below said blades'has been placedwithin thepath ofmove'ment of the reciprocating slide, which forces the same from within the holder through its outlet opening and moves the'can end within one of the aperturedopenings 5 positioned to receive the same while the turret 3 is'at a state of rest. The can end is moved within the sphere of the. apertured opening 5 through a radial cut out section inthe under face of the turret 3 adjacent each'opening 5 and during its inward movement it slides on the upper surface of thepbed 20f the machine. It will be understood that as the slide 39' is moved outwardly the rolls 12' are engaged by the-head thereof and separated or forced apart, causing the free ends of the cut out blades fulcrumed to the bracket 11 at 13, Fig. 1 of the drawings to swing inwardly within the holder 10 beneath the stack of can ends to support the same as the slide 39 moves from beneath the same. But the blades at this time out out the lowermost can end, which is. left in the path of theslide, as seen in Fig. 6.

The disks of liner material are removed successively from within the holder 14 by means'of the reciprocating cut-out slide40, Fig. 4 of the'drawings, which slide is actu' ated by a fulcrumed lever 40 which is connected at its upper end by a link 41 to the said slide 40. The lever 40' is'fulcrumed at 42 toa bracket projecting from the frame of the machine and at its free inwardly projecting end carries a following roll 42' which works within the groove of a cam 43 secured to the vertical shaft 32. During the rotary motion of the said shaft 32'the lever 40 is thrown inwardly and outwardly to impart an inwardly and outwardly recipro'cating stroke to the cut-out slide 40, which moves'beneath the holder 14 and re moves the lowermost disk blank of the stack of blanks 15' contained within said holder, and delivers thecut out lowermost blank to within one of the apertured openings 6 of the turret 4, said cut-out disk during. its trans-fer from the holder through the apertureof the said disk moving beneath the overhang wall or projection 18 of the holder 14, the said disk-blankmoving within a positioned aperture 6 of the turret-4 through thei'adial cut out portion 6 in the-upper surface ofthe turret 4 adjacent to each of the apertures 6 and connecting therewith, there being provided a grooved section 6 in which the cut out blade 40 works as moved topositiona' liner disk within apositioned aperture 6, which aperture at such time stands at rest beneath theo'verhang 18 of the holder 14, and in radial alinement therewith, Figs. 1 and 4 of the drawings.

Rotary motion is imparted to the shaft 32 for actuating thedriven shaft-28 by means ofthe beveled gear 44 secured to the upper end thereof, meshing with a similar gear 44 secured to one end of the horizontally disposed drive shaft 45, Figs. 1 and 20f the drawings, there being secured to the opposite end of the drive shaft 45 a belt pulley 45 over which is adapted to travel a power belt not shown for transmitting power thereto from an outside source of supply. The drive shaft 45 is formed with a central crank section 46, to which is secured a crank head 46 Fig. 20f the drawings. and the driven shaft 28, Fig. 3 of the drawings, is also provided with a crank section 47 to which is secured a crank head 47 The crank head 47 is connected by a crank arm 48 to a vertically movable slideblock'48' which works in guideways within the frame of the machine, Fig. 3 of the drawings, and which at its upper end carries a die-ring 49, which is adapted to project or work through an aperture 49 in the bed 2 of the apparatus. The crank head 46' of the drive shaft 45 is connected by a crank arm 50 to a vertically movable or reciprocating slide block 50 which works within guide-ways of a superstructure 51, Fig. 2 of the drawings, and the said slide 50 carries at its lower end the cutting die-member 52, Figs. 2 and 9 of the drawings, which said cutting-die is surrounded by a spring held.v ejector ring 52. The vertically movable slide head 50 carries an arcuate bracket 53, Figs. 1, 2 and 9 of the drawings, which carries at its outer end and holds within the head 53 thereof a vertically disposed stem 54 of an assembling plunger 54 which is adapted on its downward stroke to move within and through one of the apertures 6 of the turret 4- when the same is positioned in registry with one of the apertures 5 of the turret 8 with a cut ring liner 16 in axial alinement with the straight outstanding flange of a can end 9, Fig. 4 of the drawings, at such time, to remove or force the ring liner 16 from off its retaining seat 16 and press the same onto the flange 16 of the can end 9, Fig. 4' of the drawings.

The turret 4 receives during a period of rest into one of its apertures 6, a disk blank 15 at the station A, of the apparatus and is thereafter transferred by the step rotation of theturret 4 to within the sphere of the die cutting members situated at the station B of the apparatus, Fig. 1 of the drawings, and after the cutting of the ring liner the same is conveyed supported within a shouldered seat of the aperture 6 by the step rotation of the turret 4 to the assembling station C, of the apparatus, by which time the unfinished flanged can end 9 delivered into one of the apertures 5 of the turret 3 at the can end feed station I), has been transferred from said station by the step rotation of the turret 3, and placed in axial alinement with the cut ring liner at the station C, where during a period of rest in the movements of the turrets 3 and 4 the assembling plunger is brought into operation by the downward movement of the slide block or head 50 to force the cut ring liner 16 from its seat 16* onto the flange 16 of the positioned can end. The assembled can end and liner is then transferred from the station C by a step rotation of the turret 3 to place the assembled member at the'station E for the grooving of the connecting wall member 16 of the can end to permit the circumferential groove 16 to retain the assembled ring liner 16 onto the flange 16 by an overhang shoulder a Fig. 10 of the drawings.

At the assembling station and above the rotatable turret 8 and ate point approximately opposite the can end feed mechanism is located a housing 55, Fig. 5 of the drawings, within which housing is mounted for rotary movement a die ring block 55, having cut on the outer face thereof the gear teeth 56. This die ring block is provided in the lower central portion thereof with a die ring 56, and within the said block 55 is mounted a spring-pressed ejector block 57. Rotary motion is imparted to the die ring head 55 from the continuously driven vertically disposed shaft 58 through the medium of the gear 56 meshing with the teeth of the said block, Figs. 3, 5, 7 and 8 of the draw ings, which said shaft at its lower end carries a gear 58 for meshing with the gear 59, secured to the upper portion of the shaft 24, and beneath the slotted head 37 of the connecting rod 37 for actuating the can end feed lever 38. The shaft 58 intermediate its length has secured thereto a gear 60 which meshes with a gear 60 secured to the lower end of a vertically disposed shaft 61, Fig. 5 of the drawings. The shaft 61 is extended through an eccentric bushing 62 and at its upper end carries a groove forming roll 62.

The said shaft 61 derives its rotary motion from the shaft 58 and in addition to its r0- tary motion it has vertical movement imparted thereto, which motion is given to the said shaft by means of a rock lever 63, Figs. 3 and 8 of the drawings, which lever is fulcrumed to a bracket 63, and carries at its outer end a following roll 64, which works within a grooved collar 65 secured to the lower end of the eccentric bushing 62. At its inner end the. rock lever 63 carries a following roll 66 which works within the peripheral groove of a cam 67 secured to the vertical shaft 68, continuous rotation being transmitted to the shaft 68 from the shaft 58 through the medium of the gear 58' meshing with the gear 68 secured to the lower end of the shaft 68. On the shaft 68 and above the peripheral grooved cam 67 is secured a cam 69, which coacts with a following roll 69 secured to one end of a lever 70, mounted for oscillation on the shaft 58, and which lever terminates in an enlarged gear segmental head 70', the teeth of which mesh with the external teeth of the segmentalbushing 62. During the rotation of the shaft 68 the cam 69, coacting with the following roll 69, oscillates the lever 70 to cause the segmental gear end thereof to actuate the eccentric bushing 62, said lever 70 rocating motion is imparted thereto duringthis continuous rotation through the medium of the rock lever 63, while eccentric motion is transmitted to the said shaft by the action of the eccentric bushing 62, for moving or throwing the forming roll 62' carried by the shaft 61 toward and from the die ring 56 of the rotating die ring head 55. The groove forming roll 62 of the shaft 61 coacts with the die ring 56 for acting against the inner surface of the connecting wall member 16 of the positioned can end 9 with its gasket liner 16 assembled relative to its flange 16 for pressing the metal thereof downwardly over the die ring 56 for the grooving of the said connecting wall member of the can end to provide an overhang a for retaining the assembled gasket liner 16 in place relative to the outstanding flange of the can end. After the completion of the grooving operation the shaft 61 through the described cam actuated mechanism is lowered to place the groove forming roll from within the sphere of the aperture 6 of the turret 3, when the spring pressed block 57 lowers or moves the finished can end with its assembled liner fully within the aperture 6, it being understood that as the shaft 61 is raised the groove forming die bears against the under-surface of the body member of the can end and moves the same upwardly from within the aperture 6 to place its vertical connecting wall member in radial alinement with the die ring 56, a portion of the peripheral wall of the outstanding flange of the can end at all times being maintained within the aperture 6 of the turret 3.

It will be noted that in the preferred embodiment of an apparatus for carrying out the described invention there are five distinct stations employed, A, being the feedlng station for delivering disks of liner material to the apertures of the intermittent rotating turret 4; B, the station at which the ring liner is cut from the disk of liner material; D, the station for the delivery of ungrooved or unfinished can ends to the apertures of the intermittently rotating turret 3; C, the station for the assembling of the ring liner relative to the flange of the can end conveyed thereto and in axial alinement with the ring liner by the intermittent or step rotation of the turret 3, and E, is the station at which the grooving of the can end is performed for securing or holding the assembled ring liner relative to the flange of the can end. I

While cutting mechanism has been illustrated for the cutting of a ring liner from disks of liner material, it is obvious that in case previously cut ring liners are fed from the holder or magazine 14 to within the apertures 6 of the turret 4, the cutting mechanism may be dispensed with, and it is also obvious that instead of utilizing disks of liner material or feeding previously cut ring liners, that a web of liner material may be utilized from which to cut the ring liners; in such case, the web of liner material being so disposed as to travel or move over the surface of the rotating turret 4t and between the same and the cutting members for the severing of a ring liner.

Where a ring liner is cut from liner material, as for instance, a disk of liner material, it is necessary that the central core piece 15 be disposed of, and for this purpose, the slide carrying the die 49 is provided with a discharge channel 48 which communicates with an aperture 15 through which the core piece falls into the discharge channel 18 Figs. 3 and 9 of the drawings.

After the grooving of the can end for the retention of the gasket ring liner, the step rotation of the turret 3 advances the can end above the discharge chute 3 Fig. 4c of the drawings, at which point the can end falls from within the aperture 5 of the turret 3.

While the apparatus for carrying out the invention has been disclosed in its preferred embodiment, I do not wish to be understood as confining or limiting myself to the details of the working parts herein shown and described, but on the contrary wish to be understood as claiming the invention as broadly as the state of the art will permit.
